Definitions

• Aqueous cleaning compositions exhibit a tendency toward foaming because they contain surface active agents such as soaps, and synthetic detergents. In many instances, such cleaning compositions produce excessive foam and the user must use substances known as anti-foaming agents or defoamers. Some defoamers such as silicones tend to interfere with the function of the cleaning compositions in that unwanted residues are left after the cleaners are wiped off while others are environmentally unacceptable because they are not biodegradable. The unwanted residues are cloudy and reduce the shine or gloss of the surface that has been cleaned.
• Alkyl polyglycosides are a class of nonionic surfactants that exhibit significantly higher foaming profiles than other nonionic surfactants, such as alcohol ethoxylates.
• foaming tendencies of alkyl polyglycosides more closely resemble those of anionic surfactants, such as alcohol sulfates, than the foaming tendencies of other nonionic surfactants.
• This higher foaming tendency makes the use of alkyl polyglycosides undesirable for many applications, e.g., cleaning-in-place for food processing plants, high pressure spray cleaning, bottle washing, floor cleaners and automatic dishwashing, wherein high levels of foam interfere with the cleaning and rinsing operation and reduce the efficiency of the operation.
• alkyl polyglycosides are much better then other surfactants.
• the residue left behind by the alkyl polyglycosides is generally clear and colorless and reduces the shine of the surface that has just been cleaned by only a few percent.
• Low foam nonionics such as ethoxylated/propoxylated block copolymers, can be used to reduce the foaming properties of alkyl polyglycoside surfactants, but these materials have undesirable properties, e.g., low biodegradability, relatively high aquatic toxicity and poor caustic compatibility.

• auxiliary components may also be added to the above-described cleaning composition, without departing from the spirit of the invention. These include, but are not limited to, a dye component, a perfume component, and the like.
• One advantage of the above-described cleaning composition is that it does not require the presence of a preservative in order to prolong its shelf life.
• the gloss retention additive/surfactant compositions of the invention also have the following advantages:
• compositions containing alkyl polyglycosides as the surfactant provide excellent low foam profiles at low temperatures, unlike other low foam nonionic surfactants which are usually low foaming only at higher temperatures.
• the gloss retention additive/surfactant compositions of the invention can be used in a wide range of applications, including but not limited to cleaning-in-place, e.g., bottling plants (bottle wash cleaning), food processing, and the like; machine dishwashing powders and liquids used for consumer as well as industrial purposes; flooring and wall cleaners for consumer, industrial, and institutional needs; metal cleaning including aqueous bath, soak cleaning, and high pressure spray cleaning; low foam or foam controlled laundry detergent compositions for consumer, industrial, and institutional uses; ultrasonic aqueous cleaning purposes; and the like.
• cleaning-in-place e.g., bottling plants (bottle wash cleaning), food processing, and the like
• machine dishwashing powders and liquids used for consumer as well as industrial purposes
• flooring and wall cleaners for consumer, industrial, and institutional
• a cleansing wipe made from a woven and/or non-woven material which contains a cleaning effective amount of the hard surface cleaning composition of the present invention.
• Ready-to-use cleansing wipes which contain a cleaning solution within the wipe and can be readily removed from a container and used to immediately clean a surface are growing in popularity. Since these wipes already contain the necessary cleaning solution absorbed therein, this eliminates the need for having to use a separate container from which the cleaning solution is discharged onto a soiled surface, and a separate substrate with which to wipe the soiled surface.
• the types of woven and/or non-woven substrates (wipes) commonly used to carry a cleaning solution are well known in the industry.
• the gloss of the clean tiles was measured using Gardner Micro-Tri-Gloss at a 20° angle of incidence. Ten measurements were made on each tile and averaged to yield the initial gloss for each tile.
• test solution 15 drops were placed on each tile using a disposable pipette.
• test solution was spread over each tile surface by 20 cycles with a folded kimwipe tissue.
• each tile was again wiped for 20 cycles with a new folded kimwipe tissue, or allowed to air dry.
• the mixture of the gloss retention additive from example 1 and GLUCOPON® 220N were combined in a ratio of 2.4:1 active ingredients of GLUCOPON® 220N to gloss retention additive. This mixture was then diluted with water to produce a solution of 1% active ingredients. Gloss tests were carried out on the 1% active solution, the gloss retention additive alone (1% active in water), and the GLUCOPON® 220N alone (1% active in water).
• gloss retention additive from example 1 and GLUCOPON® 425N were combined in a ratio of 9.5:1 active ingredients of GLUCOPON® 425N to gloss retention additive. This mixture was then diluted with water to produce a solution of 1% active-ingredients. Gloss tests were carried out on the 1% active solution, the gloss retention additive alone (1% active in water), and the GLUCOPON® 425N alone (1% active in water).
• gloss retention additive from example 1 and GLUCOPON® 425N were combined in a ratio of 4.5:1 active ingredients of GLUCOPON® 425N to gloss retention additive. This mixture was then diluted with water to produce a solution of 1% active ingredients. Detergency tests were carried out on the 1% active solution and the GLUCOPON® 425N alone (1% active in water) using the following method.
• test soil, H6 was made up of 50 parts kerosene, 5 parts vegetable oil, 7 parts mineral oil, 25 parts brandy black clay and 1 part carbon black.
• a hard surface cleaning composition in accordance with the present invention was formulated, the ingredients of which are found in Table 1, below.
• GLUCOPON® 425N is a C8-C16 alkyl polyglycoside having a degree of polymerization of from about 1.4 to about 1.5.
• DEHYPON® ST-15 is the reaction product of an ethoxylated C8-C10 linear fatty alcohol having 4.5 moles of EO, reacted with epichlorohydrin.
• SULFOTEX® 110 is a C10 fatty alcohol sulfate.
